TYPE-WRITING MACHINE.

Specification of Letters Patent.

Application filed October 30,1903. Serial No. 179,153.

Patented March 27,?1906.

To all whom it may concern:

Be it known that I, LOUIS NEY, a citizen of the United States, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new. and useful Im rovements in T e-Writing Machines,'of W ich the following is a specification.

My invention relates to type-writing machines, and more'particul'arly to type-bars 1 and hangers therefor.

I simpleand eflicient t I ,is excluded and in which theconstruc'tion oo- The object of my invention is to provide a e-bar and hanger constr'uction wherein eac type-bar is adapted to vibrate on ball-bearings from which dust cupies' but' little space laterally,.whe reby a large number of type-b are and hangers can be mountedin a comparatively small space without unduly crowding the parts or deftracting from the, strength or rigidity thereof.

. i like reference characters designate like-parts in .the various'views, Figure 1 is a vertical front to rear sectional view of sufficient numon'thelinea w of ber of parts of one form of type-writing machines to illustrate my invention in its applie cation thereto. Fig, 2 is an enlarged detail fragmentary transverse sectional view of a type-bar and hanger, the-se'ction'being taken ig. '1 and looking in the direction of the arrow at said line. :Fig. 3 is a detailside view of a type-bar and hanger with thecove'ror bearing plate removed. -Fig. 4

p is va-view of a type-bar and hanger, on an enlaifg'ed scale and ooking in the opposite direction. I Y The frame :1 of the machine is provided with corner-posts 2 and atop plate'3. A,

, suitablecarnage- (not shown) travels from side to side of the machine on the top plate and carries a lawn 4. (Diagrammatically illustrated in Fig.1 Key-levers 5 are pivoted in the basebf the niachineiatfi and-provided with" the usua restoring-springs'i 7. .Eac'h 'ries of segmenta key-lever'is pivoted at 8 to a sublever 9, the

key-lever is pivoted at 12 to a forwardly-extending link 13, pivoted'at l i'to a type-bar '15.' The varioust 'e-bars'are segmentally arranged and are a apted to swing upwardly and rearwardly to strike the front face of-the platen 4. A ty e-bar segment 16 has a se-- l slots 17 therein, and a segmental cover-plate 18 is secured to the segment in front of the slots and constitute the front walls thereof. This cover-plate has a series of threaded openings therein, an open,-

ing being provided in front of each slot for;

the reception of a screw 19. The slots-17am each adapted to receive the stem. 20 ofa typebar hanger and'whi'ch is secured in place by a screw 19. The hanger is provided with an lower end of which is slottedat 10 for c06per ation with a fixed fulcrum-bar 11, that ex .tends from side to side of the machine be nea'th the key-levers. I The upper end of each eye 21, thathas an inwardly-beveled ball- 1 bearing faceor su'rface22 atone side thereof.

Thefe e is likewise-internally screw-threaded,

as in icated at 23, for cooperation with the external screw-threads on the'cover or bear ing plate 251. This bearinglate is provided with an inwardly-beveled all-bearing surface 25 and with a groove or slot 26, which,

may extendinto or entirely through'the coverplate and is adapted to receive a suit ablev tool, such as a screw-driver, by means of which the plate may be screwed into posi-.- tion and properly adjusted.

From an examination of'Fig. 2 be observed that the oppositely-disposed bev eled ball-bearing surfaces. 22 and 25 form-a substantially V -shapedraceway in; the me.

dian plane of the hanger for therec'eption of antifriction balls or rollers 27'. Each t e-bar 15 is apertured for thereception o a stem 28, which pro'ects from a. hub 29. The stem is projecte through its,

opening in the type-bar and is riveted thereto, as indicated at 30, in. order to securely unite the hub to thetype-bar. The hub 29 is offset from the type-bar, as, indicated in"- Fig, 2, and isprovide in the periphery therel of with a V-shaped ball-bearing groove 3 1- for cooperation with the balls 27. It wilLbe observed that the oflset hub is adapted to be.

' be brought received within the eye of the type-barhanger What I claim as new, and desire to secure and that when the balls are in g ace they preby Letters Patent, is

vent the withdrawal of the hu from the eye.

From an inspection of Figs. 2 and 4 it will be seen that the only s aceor entrance to the ball-bearing is the smai periphery of the hub an thebearmg 22 in the eye of the hanger and that the type-bar overlaps and covers this opening and pre vents the admission of dust to the bearing-at one side thereof.

the bearing, so that the hub and ring will not into contact, and that the space '32 may therefore be very small.

The bearing or cover late 24 covers one end of the hub and exclu es the admission of dust to the raceway or bearings at one side 'ment ofthe cover thereof, whereas the body portion of the t ebarcovers the opening 32 at the other si' e of the raceway and prevents the admission of dust at that side, as above pointed out, so that dust is efiicientlyexcluded. .An adjustor bearing plate 24 aflords a relative adjustment between the ball-bear cover'p sembled mg faces 22 and 25 and parallel to the median plane of the series of balls 27, thereby comensatingfor any'wear that may take place. urthermore,

wholly within the eye of the hanger and adds nothing tothe thickness thereof, so that a comparatively thin and eflicient type-bar and hanger construction'is rovided wherein dust is excluded from the bearings and antifrict'ion-balls. The wide extent of bearing-surface afforded by the circular series of antifriction-balls the ty e-bar thereo In assemblin the antifrictiori-bal s, an

in the manner shown i 2, and

the stem 28 is then introduced into t e opening in the type-bar, and the head of the stem is riveted to the bar to securely unite the hub and bar. The bearingscrewed into osition and be observed-t at the remova plate 24 is then their bearings.

An inspection-of'Fig-2 will show that there is'no contact-Whatever between the type-bar anger notwithstanding the'fact that the bod of the bar overlaps and breaks joint 'with t e o' ening 32, thereby preventlng admission of ust to the'bearing.

From certain aspects of my invention the hanger may be said to comprise a two-part eye,.one part bein formed b the opening or .eye proper, 21, and the other by the bearing or ate 24- Vanous changes may be made without departing from the spirit of my invention.
